FEEDER FOR PRINTING-PRESSES- SPECIFICATION forming part of LettersPatent No. 763,195, dated June 21, 1904.

I Application filed November 17, 1902. Serial No. 131,611. (No model.)

-To all whom it may concern:

Be it known that I, THEODORE C. MERZ, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Feeders for Printing-Presses; andI declare the following to be a full, clear, and exact descriptionof theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference ..being had to theaccompanying drawings,

nary and usual employment of presses of this class the paper is cut tosize and placed manually on the platen, and the object of thisattachment is to enable this class of presses to be used to make animprint on paper that is in longstrips and is fed from a roll. Anadjunct to the attachment is arranged to cut the paper after the imprinthas been made, and the attachmentis arranged to be adjustable, so thatthe severing of the paper may corre spond with the surface of theimprint and that the paper may be fed to correspond with. the imprint,making it possible to print sheets that in their completed condition areof any one of several different sizes. 7

In the drawings, Flgure 1 is a section somewhat diagrammatic incharacter, showing the location of the attachment with respect to thepress. Fig. 2 is an elevation of the upper part of the attachment asseen by one standing at the left of the machine as indicated in Fig. 3is a detail side elevation of one of the cam-wheels. Fig.4 is anelevation showing the attachment in substantially the same position thatit appears in Fig. 1, but on a large scale. Fig. 5 is a detail of therockshaft mechanism which actuates the grips. Fig. 6 is a perspective ofthe paper-grips. Fig. 7 is a section showing in detail the part B ofFig. 6. Fig. 8 is asectiontaken at rightangles to that of Fig. 7,showing in detail the part B of Fig. 6. Fig. 9 is a plan of the partsbeneath the table.

F indicates a frame arranged to be supported by a leg 2, that isterminated with a caster-wheel, and to be attached to and heldprincipally by the framework of an ordinary Gordon press G. The press isprovided with a driving-wheel g, which meshes with wheel 3 on theattachment, and the wheel 3 is mounted on shaft 4, to which there is acountershaft 8, both mounted on the framework F. On the shaft 4 is apinion 4 that meshes with wheel 7 on the counter-shaft 8 and produces arotation of the shaft 8 which is of speed equal to that of thedriving-wheel of the Gordon press. On the shaft 8 are cams 5 and 6, andof these cam 5 drives the mechanism which grips the paper and whichfeeds the paper, and cam 6 drives a mechanism which actuates thesevering-shears. The paperfeeding mechanism is reciprocated by a le ver6, pivotally secured to the leg 2 and provided with a carrying-pin uponwhich there is a friction-roller 2, that engages ina socket 6 on thereciprocating part of the paper-feeding mechanism. The lever 6, pivotedto the leg 2 at 62, is itself oscillated by a jointed link composed oftwo parts 6 and 6 pivoted together at 61 and adjustably pivoted at 63 toa branch 64 of the lever 6. The part 6 of the link is slotted andthrough the slot engages the wrist-pin 6 of a crank 65 on the shaft 8.The end of the link 6 which carries the pin 61, has an invariable throw;but the link 6 is adjustable along the arm 64 between its fulcrum-pin 62and the free end of the arm 64, and by means of this adjustment thethrow of the end of the lever 6 which carries the pin 2 can be variedwithin limits determined by the point of connection between the pin 63and the arm 64, and this is adjusted by a screw 6 journaled on the arm64 and traveling through a nut on the pin 63.

The feed-carriage reciprocates on a pair of guide-bars, one of which, 6,is seen in Fig. 4 and in Fig. 6, and the guide-bar 6 is itself groovedlongitudinally, and a feather on a cam 6, which travels with thecarriage, engages in the groove. The traveling carriage is composed of across-bar 5, capable of slight oscillation, and of an under grip-bar 5",held to the cross-bar 5 by yoke-like hangers A. At the end of thecross-bar 5 is a crank-arm 5", that engages with the cam 6 and producesan oscillating movement of the bar 5, which is communicated from the cam5 through a lever 5", pivotally supported on the frame part T of theframe and connected by link 5 to the crank-arm 5 on the guide 6. Anupper clamp 7 (seen best in Figs. 7 and 8) is pivotally supported by thehanger B and connected by a link 5 to a split ring 5*, that is clampedto the rod 5 Oscillation of the guide-rod 6 and of the cam 6 carriedthereon produces an oscillation of the arm 5 and of the rod 5, withwhich it is connected, oscillates the split ring 5 actuates the link 5,and actuates the upper clamp-plate 5 At the end of the rod 6 is a secondcam 71, similar to the cam 6 and arranged to engage a crank-arm 72 on across-rod 5 that is similar to the cross-rod 5, except that it does nottravel, but remains substantially fixed except for its oscillation. Onthis cross-rod 5 is a hanger B, which supports an upper grip-plate 7 andembraces a lower fixed grip-plate 7 actuated by split ring 7 similar inall respects to the corresponding mechanism described in connection withthe hanger A. On the rod 5 is a second hanger O and connected grippingmechanism similar to the already-described gripping mechanism, and thesehangers are both adjustable along the rod 5 -to accommodate the wiclthof the paper that is to be used. The paper lies between them, above theunder plate 5 and below the upper gripping-plate 5, which extends towardthe hanger C only far enough to enable it to properly grip the edge ofthe paper. A hanger D on the rod 5 has connected with it mechanism inall-respects similar to the gripping mechanism of the hanger B, theupper gripping-foot being pointed toward the hanger B and the uppergripping-foot 7 f of the hanger B being pointed toward the hanger D. Thecams 6 and 71 are set so that the gripping parts of the hangers B and Dseize upon the paper just at the point of time when the carriage hasadvanced most closely to them and is about to recede,andcontemporaneously with the seizing of the paper by the gripping partsof the hangers B and D the gripping parts of the hangers A and O releasetheir hold and the carriage travels backward, sliding freely over thepaper.

When the carriage has reached the rearmost.

point of its travel, its gripping parts seize the paper, the grips ofthe hangers B and D release the paper, and the carriage returns forward,drawing the paper with it. It will be observed that the gripping partsseize the paper when the carriage has reached the rearmost point of itstravel in any adjusted position.

To the end E of the frame-pieces T is adjustably secured a frame whichcarries the shears or severing knife. This frame is held by sliding arms21, that engage in grooves on the under side of the frame-pieces T andare held in adjusted position by holding-screws 22. The shears-blade isheld in slotted standards 23 and 24 and is actuated by links 25 and 26,that are pivotally connected to levers 27 and 28. The two levers 27 and28 are linked together by a link 29 and are actuated contemporaneouslyby a crank-pin 30, that engages in cam 6. The crank-pin 30 is on abranch arm from the lever 27, and the lever 27 is pivotally secured to ahanger from the cross-bar R of the frame, and the lever 28 is alsopivotally secured to a hanger from the same cross-bar. The cutting-knife31 is arranged obliquely with respect to the fixed plate 32, so thatwhile its motion is nearly vertical it has a shearing cut and isactuated from the same shaft 8 that actuates the feed mechanism andmakes a cutting reciprocation with each forward motion of the feedingapparatus. The position of the cut with respect to the paper and theimprint made on the paper is determined by adjustment of the shearingmechanism with respect :to the main frame of the attachment.

What I claim is 1. In an attachment for printin -presses, a rock-shaft,a cross-head adapted to reciprocate longitudinally to said shaft, agripper mechanism connected with said cross-head and connected with saidrock-shaft so as to be capable of sliding longitudinally thereto and tobe operated by the rocking of said shaft, means for reciprocating saidcrosshead, means for rocking said shaft, and a stationary grippermechanism vadapted to be operated alternately to the first-named grippermechanism, by the rocking of said shaft, for the purpose described.

2. In an attachment for printing-presses, a rock-shaft, a cross-headadapted to reciprocate longitudinally to said shaft, alaterallyextending rock-shaft on said cross-head adapted to be rocked bythe rocking of said firstnamed rock-shaft, a gripper mechanism on saidtransverse rock-shaft adapted .to be .adjusted longitudinally theretoand to be operated by the rocking thereof, means for reciprocating saidcross-head and means for rocking said shafts.

3. In an attachment for printing-presses, a cross-head, means forreciprocating saidcrosshead, a rock-shaft upon said cross-head extendingtransversely to the motion thereof, a gripper mechanism upon said crosshead adapted to be operated by said rock-shaft and adjustablelongitudinally of said shaft, means for reciprocating said cross-headand means for rocking said shaft.

4. In a printing-press feeder, the combination of a reciprocatingcross-head, a gripper mechanism on said cross-head adjustable lat- IOsaid part adjustable longitudinally thereto,

and means for automatically actuating said jaw in any position in itssaid ad ustment and at any position in the reciprocating movement.

In testimony whereof I sign this specifica- 5 tion in the presence oftwo witnesses.
